Benchmark Capital is one of Uber's original investors and has been on board through thick and thin, expecting to sell its holdings for an Uber valued at around $100 billion. However, the SoftBank deal required all investors to sell them 14.5% of their holdings, to give SoftBank the necessary board presence they required for their $10billion investment.

When investors are given a choice, sell and make a profit or stay and maybe make an even bigger profit in the future, they tend to weigh their personal needs before the company needs that they are invested in. With Uber, this is increased...

Benchmark own 13% of Uber and sold only 14.5% of its holdings for $900 million at a share value of $48billion. This means that Benchmark still holds over 11% in Uber, and shows a massive profit since it only invested $373 million in two early rounds.

Google Ventures also cashed out 14.5% of their holdings for $350 million. Google is currently involved in a major lawsuit via their autonomous vehicle company Waymo. Google Ventures held 5% of Uber before the sale.

Apart from the many employees of Uber that have cashed out and became overnight millionaires, Travis Kalanick sold around $1.4 billion worth of his holdings, Garrett Camp will sell 15% of his shares giving him a whopping $400 million, First Round Capital will sell 36% of its holdings, and Menlo Ventures will sell 46% of its shares in Uber. All sold at the reduced price, but all made a great amount of money since they were invested in Uber from its early development stage.

There are a few non-sellers, and they include Kleiner Perkins Caulfield and Byers, and Lowercase Capital.
